MF_CAPTURE_ENGINE_EVENT_GENERATOR_GUID attribute

Identifies the component that generated a capture event.

Data type

GUID

Remarks

This attribute appears on some events from the capture engine. To get this attribute, call IMFAttributes::GetGUID on the event object. The event object is passed to the application through the IMFCaptureEngineOnEventCallback::OnEvent method.

The value is an interface identifier for the component that generated the event. For example, the value IID_IMFCapturePreviewSink indicates the preview sink (IMFCapturePreviewSink). Not every capture event contains this attribute.
